5 common valves used in oil and gas
Sep 16, 2024
They can be used to control flow rate, isolate and protect equipment, and guide and direct the refining process of crude oil. In this article, we will discuss 5 common valves used in the oil and gas industry.
1. Pneumatic control valve Pneumatic control valve is a valve that provides process control for flow rate, pressure, and temperature in the petroleum and natural gas industry. They work by changing the size of the flow channel based on hydraulic, pneumatic, or electrical signals sent from the controller. The automatic operation of these valves allows them to be remotely operated, rather than constantly monitored and adjusted by operators.
2. Electric control valves are used to isolate and regulate various media with low pressure loss. Valves are usually equipped with actuators. Their thickness is very small and can be placed almost anywhere, while the ease of use of larger diameters means they can be used in large pipelines. At startup, they can be quickly opened and closed, providing high reliability and requiring almost no maintenance.
3. Air safety valves are designed to control the flow of high-pressure liquids and gases while minimizing pressure drop. They can be quickly opened and closed, and have a tight seal with low torque. They are easy to operate, maintain, and multifunctional, making them suitable for use in various places.
4. Check if the valve eccentric rotation regulating valve is used to prevent reverse flow in the pipeline. Their services help protect pumps and equipment that may be damaged due to backflow, thereby reducing system maintenance and downtime. The pressure drop of these valves is very low, which can save energy. They also help reduce vibrations inside the pipeline.
5. Valve positioners are commonly used for isolation and throttling services. Due to the easy processing and simple installation of the valve seat. They have a tight closing ability, and simple linear motion can quickly open and close valves
